Hello Mike,
Are you aware that the requirement that blk-mq drivers rerun the queue after
having returned BLK_MQ_RQ_QUEUE_BUSY is a requirement that is shared with
traditional block drivers? From dm_old_request_fn():
if (... || (ti->type->busy && ti->type->busy(ti))) {
blk_delay_queue(q, 10);
return;
}
Bart.
